ORP PROBE MAINTENANCE
ORP probes should be periodically cleaned for best performance. The period
between cleanings is up to the user but typically every 1-3 months is normal. To
clean the probe, gently brush the sides and tip of the probe with a soft brush to
remove any debris. Rinse the probe in tap water. Soaking the probe in acid
(vinegar) or alkali (borax) solution to remove mineral deposits is not typically
needed but can be used to try and bring back an old probe that has stopped
working.
CONDUCTIVITY PROBE SETUP (OPTIONAL)
A port to connect a Conductivity probe is included on the optional expansion
Probe Module 2 (PM2). The Conductivity probe will be identified as “Condx3”,
“Condx4”, etc on the Apex system. The number in the probe identifier
corresponds to the AquaBus number assigned to the PM2. If a temperature probe
is connected to the PM2, it is identified as “Tmpx3”, “Tmpx4”, etc. with the same
AquaBus number as the conductivity probe.
NOTE: The AquaController Apex firmware version must be at least version 4.02
to support the Probe Module 2.
The PM2 connects to the Apex system via AquaBus. It does not matter into which
AquaBus connector it is plugged into. When the probe module has been
successfully added to the system the status light will change from flashing yellow
to solid green.
NOTE: The Conductivity reading can be added to the Apex Display and Web
Interface Status Screens. See the section titled Display Setup for more
information.
To enable the Conductivity probe:
Apex Display: Setup – Cond Setup – Cond Enable – If you have more than
one Conductivity port on your system, use the up/down arrow keys to
choose the port you wish to configure, press Select, then use the up/down
arrow keys to select on/off for that port, press OK when done or Exit to
discard changes.
Web Interface: This option is not available from the Web Interface.
